We use the Garmin Dezl 760LMT in our Newmar 4369, and prefer to stay off major highways as we full time across the country. In the four years we have been using this unit it has only misdirected us twice. Once, it told us to take a dirt road to a campground, and once it told us the campground was 1/4 mile further down the road when I was turning into the campground entry. Neither of those directives proved disastrous. When in doubt about the course the Garmin has told us to follow, we rely upon Google maps on our phones to provide us a second opinion, or, if in an area where cell service is unavailable, I use my Garmin handheld. So far, seven years on the road has been a blast, with no issues having been caused by our navigation methods
